IMPROVEMENT IN COTTON-CLEANERS.

Specification forming part of Letters Patent N o. I 68,282, dated September 28, 1875; application filed July 3, 1875.

To all whom it may concern:

Be it known that I, ARTHUR O. PEARCE, of Milan, in the county of Gibson and State of Tennessee, have invented a new and valu able Improvement in Cotton-Cleaners; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a front view of my cotton-cleaner. Fig. 2

is a sectional detail view of the same, and Fig.

3 is a longitudinal vertical sectional View thereof. liig. 4 is a sectional detail view.

This invention has relation to devices which are designed to remove dust, trash, or other foreign substances from cotton previously to being ginned; and the nature of the invention consists in the combination of a blower arranged in a suitable casing, and a feed-table,

' the trunk; and in a secondary pipe, communicating with the first and with the dischargespout of the trunk, whereby a second current,

of less power than the first, will be obtained,

as will be hereinafter more fully explained.

In the annexed drawings, A vdesignates a two-story building, in connection with which I propose to illustrate the use and application of my improved device for cleaning cotton before it is ginned. This building is divided by a close flooring, a, into two stories, as shown in Fig. 1. In this building is arranged a receiving-trunk, B, which is partly in the upper and partly in the lower story, which trunk is provided upon its lower end with a tapering discharging-spout, a, and upon its upper end with an eduction-spout, b, which is also of tapering form, and is separated from the body of the trunk by means of a reticulated screen or sifter, c, for a purpose hereinafter explained. The upper part of trunk B is in the loft of the building, and communicates, by means of a pipe, C, of suitable dimensions, with the cylindrical casing I) of a blower'wheel, F, arranged in suitable bearings in the said casing, which is situated in the lower part of the said building. Casing D communicates, by means of a conduit, E, with a feed-table, G, which is in the nature of a hopper, and serves to receive the unginned cotton. Motion is imparted to blower F through the medium of an endless belt, H, passing over an actuating-pulley, I, keyed upon the end of the shaft of the said farnby means of a suitable motor; and if, during the rotation of the said fan-blower, un-

' ginned cotton be placed upon the feed-table,

it will be sucked down conduit E, and forced up pipe C to trunk B, being subjected during its ascent thereto to a strong blast of air, which will effectually remove dust, grass, or other foreign substances, and will gravitate downward through discharging-spout a.

When the cotton under treatment is discharged from pipe G into receptacle B, reticulated screen 0 will' prevent it from being discharged through spout b into the open air, but will allow the dust to have free egress thereto.

With a view to subjecting the descending cotton to a second cleansing before being allowed to escape from the lower end ofspout a, I make use of a second conduit, J, which communicates with pipe C and with the tapering spout a of the receiving-trunk B, up which a constant current of air is driven-by a fan-blower, F, thereby effectually driving the remaining impurities in the cotton upward through sitter c and eduction-spout 1) into the open air. Conduit J and pipe 0 are separated by means of a screen, d, from each other, which screen is of a suitable reticulated material, and will allow the air to pass freely through it, while it will prevent the exit of cotton, which is thereby directed up pipe G into receivingtrunk B. The cotton will, under ordinary circumstances, gravitate through trunk B and its tapering spout a, in spite of the current of air driven into the latter through conduit C but as, under certain conditions, this blast might be of a strength sutficient to retard the escape of the substance treated, conduit J is provided with a regulating-valve, V, by means of which the power of the blast may be increased or diminished, as the circumstances of the case may require.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the trunk B, having discharge-chute a, of the primary blast-pipe G and secondary pipe J, the latter provided with regulating-valve V, substantially as specifled.

2. The combination, with a receiving-trunk, B, a primary blast pipe, 0, a secondary airconduit, J, and screen d, or" a regulating-valve,-

V, and a blowing-fan, F, substantially as specifled.

pipe, 0, and a secondary conduit, J, of the reticulated screen 61 and valve v, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
